I don't have a solution but I have been experiencing this problem from time to time. If I understood correctly, this instance of gnome-shell (user Debian-+) is associated with the operation of gdm3, i.e. it's "gnome-shell --mode=gdm". The gnome-shell you work directly with is run under your own username, cf. ps aux | grep gnome-shell. I'm finding that a reboot resets Debian-+ gnome-shell back to normal cpu usage. I wonder if the CPU overload comes either from a bad state after a few suspend/resume cycles, or if it happens due to library inconsistencies after upgrading gnome or xorg packages without rebooting.
